My Fair Lady Designs http://www.myfairladydesigns.com/
Shelly Smola is an awesome designer of machine embroidery designs. I love, love, love her designs. They are cute, yet classy. Shelly's instructions for using her designs in projects are THE BEST. They are so clear, detailed, and helpful. You'll find lots of photos to help you. To top it off, Shelly is one of the sweetest people I know. Her designs are affordable and fairly priced. Check it out. You will not be disappointed in the quality of the designs and how they stitch out.

Evy Hawkins also has great, classy designs. Evy also writes great directions. Like Shelly, Evy is well published in the machine embroidery magazines. This page links to her shop (Absolutely Sew). The quality of the designs are incredible, and Evy and her son, Zach are awesome.
The Ribbon Retreat http://www.theribbonretreat.com/
This website has great ribbons and wonderful free tutorials on how to make cute barrettes, pony tails, and head bands using ribbon. So cute.
The Ribbon Jar http://www.ribbonjar.com/
A source for fantastic ribbons, all packaged together so nicely in vintage glass jars. I love this site!
Jinny Beyer Studio http://www.jinnybeyer.com/
Jinny Beyer Studio is a great resource for border stripe fabrics and all around fantastic fabrics. She has many wonderful patterns based on tessellations and kaleidoscopes. Great resource for her books, too.
The Quilt Show http://www.thequiltshow.com/
This is the website that really got me hooked on on-line communities. Alex Anderson and Ricky Tims produce a high quality "TV" show you can stream over the web. You have to join and pay a reasonable fee to watch the shows, but it's well worth it. There are wonderful quilting communities here, too...blogs, discussion boards, show and tell... Quilt galleries, too!
Paula's Kit Club http://www.paulaskitclub.com/
Paula Montgomery used to co-own Rubber Baby Buggy Bumpers rubber stamp company, a really awesome off-beat rubber stamp store. I was so disappointed when she closed it down, but was more than excited when she started Paula's Kit Club instead. You can sign up for monthly kits, which include awesome scrapbooking paper, ribbon, ephemera, a rubber stamp (if you elect for this option), charms, beads, and the like. All kits are centered around a theme, and she has wonderful samples on her website so you can see what to do with the materials. Paula has a great sense of humor and is a joy to interact with. Highly recommended.
The Fabric Bar http://www.thefabricbar.com/index.html
This website has some really cute fabrics, ribbons, and twill/linen tapes. A very unique style that is a Japanese feeling for many items. The rest is just very artsy and different than what you are accustomed to. Not even sure how to describe it. 1950's retro? Something like that...
